Nasogastric feeding tube may be placed for feeding. After stabilisation, you could be discharged from hospital later. You need to regular follow up in hospital after discharge for monitoring your progress. You may need a surgery later.

Yes, there is a need to worry. You should be in routine followup If any difficulty in swallowing, repeat endoscopy or dilatation willbe required. If no improvement, surgery may be required.
